Hedera Hashgraph (HBAR): Distributed Ledger Technology Explained

Hedera is governed by some of the largest enterprises on the planet. And it is quietly becoming the infrastructure layer for real-world tokenisation, AI governance, and cross-border settlement. Whether you hold HBAR, build on the network, or just want to understand what the noise is about, this is the Hedera guide you need.

Hedera Hashgraph: Quick Overview

Hedera is a public distributed ledger built on hashgraph technology, not a blockchain. It was designed from the ground up for enterprise use. Here is what makes it distinct at a glance:

• Consensus mechanism: Gossip-about-gossip and virtual voting, achieving asynchronous Byzantine Fault Tolerance (aBFT)
• Data structure: Directed Acyclic Graph (DAG), not a chain of blocks
• Throughput: Over 10,000 transactions per second for native token and consensus services
• Finality: Deterministic, typically under five seconds
• Transaction fees: Fixed at around $0.0001 USD, pegged to USD not HBAR price
• Governance: The Hedera Governing Council, comprising up to 39 global enterprises
• Energy use: Carbon negative, among the most efficient public networks measured

What Is Hedera (HBAR)?

Hedera is a distributed ledger technology, not a blockchain. While it shares the same broad purpose as networks like Bitcoin and Ethereum, Hedera is built on a fundamentally different architecture with a different set of priorities.

The network is public. Anyone can build on it, hold HBAR, or stake to a node. Where Hedera diverges from most public networks is in its design brief. It was built specifically for enterprise-grade applications that require deterministic finality, predictable transaction costs, and governance structures that institutions can trust and audit.

Hedera is known for high throughput, low fixed fees, energy efficiency, and a governance model backed by some of the world's largest enterprises. It is also known for a permissioned node structure that limits who can validate transactions, a consensus algorithm that is newer and less battle-tested than Bitcoin or Ethereum, and a token (HBAR) with a large maximum supply that has yet to fully convert enterprise activity into sustained price performance. Both sides of that picture matter if you are trying to understand what Hedera actually is.

‍What Is Distributed Ledger Technology (DLT)?

A distributed ledger is a database with no central owner. Instead of one entity holding the master copy, the record is shared across many participants simultaneously. Every participant maintains their own copy. When a new transaction is added, it is propagated across the network so every copy updates and stays in sync.

Most people encounter distributed ledger technology, or DLT, through blockchains. Bitcoin and Ethereum are both blockchains, and both are forms of DLT. But blockchain is one approach to the problem, not the definition of it.

Hedera uses a different data structure called a directed acyclic graph, or DAG. In a blockchain, transactions are bundled into blocks and added to a single chain in sequence. In a DAG, transactions are recorded as individual events that reference previous events, building a web of connections rather than a linear chain. That structure allows multiple transactions to be processed in parallel rather than waiting in sequence.

The practical result is higher throughput and faster finality. The trade-off is a newer, less widely understood architecture that has not yet accumulated the same depth of real-world testing as Bitcoin or Ethereum.

Who Created Hedera Hashgraph?

The hashgraph algorithm was invented by Dr. Leemon Baird around 2015. Hedera Hashgraph LLC was then co-founded by Baird and Mance Harmon in 2018 to build a public network on that technology. Baird serves as co-founder and Chief Scientist. Harmon co-founded the company and served as CEO before being elected Chairman of Hedera Council in July 2025.

The Hashgraph Consensus Mechanism

Consensus is the problem every distributed network has to solve. How do you get thousands of nodes across the world to agree on the order of transactions, without trusting any single one of them? Bitcoin solved it with proof-of-work mining. Ethereum moved to proof-of-stake. Hedera took a different path entirely:

How Does the Hedera Hashgraph Consensus Work?

The Hedera hashgraph consensus mechanism uses two interlocking concepts: gossip-about-gossip and virtual voting.

• Gossip-about-gossip means that every node shares more than just transaction data with its neighbours. It also shares information about what it has already heard from other nodes. This layered communication propagates across the network exponentially. Every node rapidly builds a complete, shared picture of all recent activity.
• Virtual voting is what makes this efficient. Once each node has that complete picture, it can independently calculate how every other node would vote. No actual vote messages need to be transmitted. Consensus is reached mathematically. The result is a network that reaches agreement fast, fairly, and without the overhead of traditional voting protocols.

How Hashgraph Enables Parallel Processing

Most blockchains process transactions sequentially. Each block is added one at a time. Every transaction waits its turn. When the network is busy, that queue backs up. The result is congestion, delayed finality, and rising fees.

Hashgraph works differently because of its underlying data structure. Instead of a single chain of blocks, the hashgraph is a Directed Acyclic Graph, or DAG. Transactions are recorded as individual events. Each event references two prior events rather than slotting into a single linear sequence. That structure means multiple transactions can be processed in parallel across the network simultaneously.

Nothing gets discarded. In a proof-of-work blockchain, blocks mined simultaneously can conflict, and one gets thrown away. In a hashgraph, every event is incorporated into the ledger. There is no wasted work.

The practical result is that Hedera's throughput is limited primarily by available bandwidth, not by the architecture itself. That is a meaningful design advantage over networks where the block structure creates a fundamental ceiling on throughput regardless of hardware improvements.

What Is aBFT (Asynchronous Byzantine Fault Tolerance)?

aBFT is the security standard underpinning Hedera's consensus. To understand why it matters, it helps to understand the progression from BFT to aBFT.

Byzantine Fault Tolerance, or BFT, refers to a network's ability to keep functioning correctly even when some participants are acting maliciously or failing entirely. The name comes from the Byzantine Generals Problem in distributed computing. The basic requirement is that as long as more than two thirds of nodes are honest, the network reaches correct consensus.

Most practical BFT systems make an important assumption: that messages will be delivered within a known time window. This is called partial synchrony. It works well under normal conditions. But if an attacker can delay or reorder messages beyond that window, they can potentially disrupt consensus. The time assumption becomes a vulnerability.

Asynchronous BFT removes that assumption entirely. The network makes no guarantees about message timing at all. Messages can be delayed, reordered, or dropped. The network still reaches correct consensus. An attacker who controls the timing of messages cannot prevent agreement or alter it once reached.

Hedera's hashgraph algorithm achieves aBFT. That claim has been formally verified. The algorithm was checked using the Coq proof assistant, a computer-verified formal proof system. The proof covers the algorithm itself, not every layer of the production implementation. What it establishes is significant: hashgraph achieves the highest theoretical security standard available in distributed systems.

Most blockchain networks offer probabilistic finality. There is always a small theoretical chance a confirmed transaction could be reversed. Hedera offers deterministic finality. Confirmed means confirmed. Each node reaches a point where it knows with certainty that consensus has been achieved, not just that it is very likely.

aBFT vs Partial Synchrony BFT: Why the Difference Matters

Networks like Tendermint and PBFT use partial synchrony BFT. They are secure under normal network conditions and have strong real-world track records. The trade-off is that their security model depends on network timing assumptions holding. Under adversarial conditions where those assumptions break down, so does the security guarantee.

Hedera's aBFT makes no timing assumptions. That is a stronger model. For enterprises building applications where a transaction reversal or consensus failure carries legal or financial consequences, that distinction is a commercial requirement, not just a technical preference.

It is worth being precise about what aBFT does and does not protect. The consensus layer achieving aBFT does not mean every part of the system is immune to failure. Hedera's 2023 smart contract exploit is a useful reminder. The consensus mechanism performed correctly. The vulnerability was at the application layer. Strong consensus guarantees and total system safety are not the same thing.

Hedera aBFT Security: Why It Matters for HBAR Holders

For enterprise users, aBFT is a commercial requirement as much as a technical one. Industries like financial services, healthcare, and supply chain need to know that a recorded transaction stays recorded. The probabilistic security model of proof-of-work blockchains does not meet that bar. Hedera's aBFT guarantee does.

For HBAR holders, it matters for a different reason. A network with deterministic finality is harder to attack and harder to manipulate. That security foundation is part of what makes the enterprise adoption story credible.

Hedera Throughput and TPS

Hedera's native token service and consensus service can handle over 10,000 transactions per second with finality in under five seconds. That figure applies to HTS token transfers and HCS operations. Smart contract execution through Hedera's EVM layer has lower throughput, as it does on all EVM-compatible networks. For context, Bitcoin processes around 7 TPS. Ethereum handles roughly 15 to 30 TPS on its base layer.

Many operations on Hedera cost around $0.0001 USD, with fees pegged to USD rather than fluctuating with token price. The exact fee depends on the service type. There is no bidding for block space and no fee spikes when the network gets busy. For enterprises running high-volume applications, that predictability is as commercially important as the speed itself.

Is Hedera a Public or Private Network?

This question comes up constantly. The confusion is understandable. The answer has changed over time and is still evolving.

Hedera launched as a public network in September 2019. Anyone can create an account, hold HBAR, and deploy applications. What has been permissioned, and still is, is the consensus node layer. Currently, only members of the Hedera Council operate or sponsor the nodes that validate transactions and write to the ledger.

Hedera's goal is to eventually allow anyone to run a node anonymously and earn HBAR for supporting the network. That transition to permissionless nodes is planned in phases. Proxy staking and widespread coin distribution are prerequisite steps. So in short, the network is public but the infrastructure is permissioned.

Is Hedera Hashgraph Quantum-Resistant?

The honest answer is: partially, and actively working on the rest.

Hedera uses cryptography aligned with CNSA-level primitives, the same class of cryptographic standards the US government uses for sensitive information. This includes 256-bit AES keys and 384-bit SHA-2 hashes. With these key sizes, Hedera's hashing infrastructure is considered safe against future quantum computers. On that front, Hedera is already ahead of most networks, which use 256-bit hashes.

The current vulnerability lies in digital signatures. The Ed25519 elliptic curve scheme Hedera currently uses for transaction signing is not quantum-resistant. Shor's Algorithm could break it on a sufficiently powerful quantum computer. Hedera is monitoring NIST's post-quantum cryptography standardisation process closely. A partnership with SEALSQ is developing quantum-resistant hardware specifically for Hedera's ecosystem. No quantum computer exists today capable of breaking current cryptography. The preparation for future threats is already underway.

The Hedera Ecosystem

Hedera is a stack of network services that developers and enterprises can use independently or in combination. Understanding the ecosystem matters if you want to assess the network's long-term utility and HBAR's value proposition.

The Hedera Token Service (HTS)

HTS enables the creation, management, and transfer of native tokens on Hedera without requiring smart contracts. That simplicity, combined with speed and low cost, makes it attractive for asset tokenisation. Real-world deployments include RedSwan's tokenisation of over $5 billion in commercial real estate, and stablecoin remittance pilots with Shinhan Bank and SCB TechX using HTS for real-time settlement. DailyCoin USDC has also been natively deployed on Hedera via Circle, giving the network one of the two dominant dollar-pegged stablecoins.

Hedera Smart Contracts

Hedera supports smart contracts written in Solidity, the same language used by Ethereum. This EVM compatibility means developers can migrate existing dApps to Hedera or build new decentralised applications without learning a new language. It also means DeFi protocols, token standards, and tooling built for Ethereum can be adapted for Hedera with relatively low friction.

Smart contracts on Hedera run through the EVM layer, which has lower throughput and higher fees than native HTS token transfers. The advantage over Ethereum is that even at the EVM layer, Hedera's fee structure is more predictable and there is no competition for block space driving costs up unpredictably. For DeFi applications where gas fee volatility has historically been a barrier to adoption, that predictability has real value.

Proxy Staking on the Hedera Network

Hedera's staking model is worth understanding in detail. It is meaningfully different from most proof-of-stake systems. And those differences have direct tax implications.

Proxy staking allows the stake of millions of account holders to contribute to consensus even without directly participating as a node. Your HBAR remains fully under your control. It is never lost, fined, or locked up. You assign the weight of your holdings to a node you trust. That node's influence in consensus increases. You receive a share of staking rewards. You can change your node or unstake at any time with no penalty.

The Hedera Council has implemented a maximum annual reward rate cap of 6.5%, with actual rates fluctuating based on total HBAR staked. Rewards are distributed daily. Those daily rewards are generally treated as taxable income in the year received, valued at fair market value on the date of receipt.

While we have a lot of guidance on how crypto is taxed in the US, the IRS has not issued explicit guidance on staking tax specifically. But crypto tax accountants and CPAa generally go with a treatment derived from general crypto income principles under Notice 2014-21, and subsequent guidance. Aggregated over a year of daily distributions, this creates a real IRS reporting obligation that most stakers including Hedera stakers, never account for.

How is HBAR staking taxed by the IRS?

HBAR staking rewards are generally treated as ordinary income in the year you receive them, valued at the fair market value of HBAR on the date of each distribution. The IRS has not issued explicit staking-specific rules, but that treatment follows from general crypto income guidance under Notice 2014-21. Because Hedera distributes rewards daily, active stakers can have hundreds of separate income events per year. When you later sell or swap the HBAR you received as rewards, any gain or loss on that disposal is also reportable. Please take proper precautions to avoid getting on the taxman's radar and scoring yourself an IRS crypto audit. Not fun.

HBAR Token and Tokenomics

What Is the HBAR Token Used For?

The Hedera token, HBAR, serves three functions on the Hedera network.

1. First, it is the fuel for network services. Every transaction, smart contract execution, and token transfer requires HBAR to pay the fee.
2. Second, it provides network security through staking. HBAR staked to nodes contributes voting weight to consensus, making the network harder to attack.
3. Third, it is the mechanism for distributing staking rewards to node operators and proxy stakers.

HBAR Tokenomics

HBAR has a fixed maximum supply of 50 billion tokens. No inflation beyond that cap. The Hedera Council manages the emission schedule via a controlled release from the treasury. Staking rewards are paid to participants from this treasury allocation, strengthening the proof-of-stake model over time.

For investors, HBAR's tokenomics create a relatively predictable supply trajectory. The more relevant variable is demand. Demand is driven by network usage, new Council members building on-chain, and the expansion of HTS-based tokenisation. More transactions mean more HBAR consumed in fees. Those fees are distributed to node operators rather than burned, so they do not permanently remove HBAR from supply. More staking means more HBAR contributing to consensus weight. Both factors increase network utility and reduce the portion of supply sitting idle.

The Hedera Council

How Does Hedera Council Governance Work?

The Hedera Governing Council rebranded as Hedera Council in May 2025, with Mance Harmon elected Chairman for a two-year term beginning July 2025. The Council is responsible for approving software updates, managing the HBAR treasury, setting network pricing, and steering strategic direction.

Governance is modelled on VISA's original 1968 structure, operated through a limited liability company agreement. The Council currently has 31 members, with a target of 39, each serving staggered three-year terms with a maximum of two consecutive terms. Exponential Science Equal voting rights regardless of company size means Google and a university research institution have identical influence. The idea is that no single entity can dominate.

Which Big Companies Run Hedera Nodes?

Council members span technology, finance, telecommunications, energy, and academia. Notable participants include Google, IBM, Dell, Boeing, Standard Bank, Deutsche Telekom, LG Electronics, Chainlink Labs, and Ubisoft. Academic institutions like the London School of Economics and University College London also sit on the Council.

Recent additions include Blockchain for Energy, focused on sustainability and emissions reporting, and Arrow Electronics, developing a global supply chain initiative. Each Council member operates or sponsors an actual network node, validating transactions and writing to the ledger. That is infrastructure commitment, not a logo on a website.

How Council Membership Works

Hedera Council members serve staggered three-year terms. A maximum of two consecutive terms is permitted. Former members may rejoin after a three-year waiting period. New members require majority approval from the existing Council. This rotation prevents entrenchment and brings fresh perspectives over time.

The Council introduced Strategic Partner and Community Partner categories in 2025. These allow organisations to participate formally in the Hedera ecosystem without taking on full membership obligations. Engagement is expanding. Governance is tightening.

Hedera (HBAR) Use Cases

Hedera in Finance and Payments

Hedera's throughput and fee predictability make it viable for real payment infrastructure. Bank pilots with Shinhan, Standard Bank, and SCB TechX are using HTS for real-time cross-border FX settlement. That is exactly the use case where existing correspondent banking infrastructure is slow, expensive, and opaque.

Hedera in Supply Chain and Sustainability

Avery Dennison's atma.io platform runs on Hedera and has tracked over 30 billion products, giving brands real-time supply chain visibility. Hyundai Motor Group uses Hedera for immutable carbon emissions tracking. The Guardian framework enables digital carbon credit management and on-chain ESG data. For enterprises facing mandatory sustainability reporting obligations, Hedera's immutable audit trail functions as a compliance tool as much as a technology choice.

Hedera for Digital Identity

Decentralised identity solutions built on Hedera allow individuals and organisations to maintain verifiable credentials without relying on a centralised issuer. EarthID and Neuron are building DID and machine-to-machine micropayment infrastructure on the network. The combination of Hedera's throughput and its enterprise governance makes it well-suited for identity applications where both scale and institutional trust matter.

Hedera, CBDCs, and Tokenised HBAR Assets

The Reserve Bank of Australia's Project Acacia selected Hedera as one of a range of DLT platforms for pilot wholesale CBDC issuance, alongside Redbelly Network, R3 Corda, Canvas Connect, and other EVM-compatible networks. RedSwan has tokenised over $5 billion in commercial real estate on HTS. Archax, a regulated platform, is issuing and trading tokenised securities and money market funds. Lloyds Banking Group have executed tokenised collateral transactions on Hedera in a UK first. This is the institutional tokenisation story that most crypto narratives miss entirely.

How Does Hedera Compare to Other Cryptocurrencies?

Hedera vs Bitcoin

Bitcoin is a store of value secured by proof-of-work mining. It processes around 7 transactions per second, has no smart contract capability on its base layer, and was never designed for enterprise applications. Hedera and Bitcoin are solving different problems. If you are assessing them as investments, the relevant question is which thesis you believe in: digital gold, or enterprise DLT infrastructure.

Hedera vs Ethereum

Ethereum is Hedera's closest conceptual competitor. Both support smart contracts. Both have active developer ecosystems. Both are targeting institutional adoption. The differences come down to performance and cost. Hedera processes native token transfers faster, with more predictable fees and no gas dynamics. Hedera also supports Solidity, so the developer tooling overlap is real. Ethereum's advantage is network effects. A far larger developer community, more DeFi liquidity, and deeper integrations. Hedera is faster and cheaper at the native layer. Ethereum is bigger and more established.

Hedera vs Solana

Solana also claims high throughput and low fees. On paper the specs look comparable. Solana has experienced multiple significant network outages under heavy load, which is a matter of historical record. Hedera's aBFT consensus is designed to maintain operation even under adversarial conditions. For enterprises that need uptime guarantees, that distinction carries real commercial weight. For more on the pros and cons of Solana, check out my updated guide.

Is HBAR Better Than XRP?

XRP and HBAR occupy adjacent but distinct positions. XRP is purpose-built for bank-to-bank cross-border settlement, with deep existing relationships at the correspondent banking layer. HBAR is a broader infrastructure platform. Settlement is one use case among many, alongside tokenisation, identity, AI governance, and supply chain. XRP has more existing banking integrations today. HBAR has a more diverse application surface. They represent different bets on how institutional DLT adoption plays out.

Can Hedera (HBAR) Reach $10?

I'll be direct. A $10 HBAR price would require a market capitalisation of approximately $500 billion at full token supply. That would make HBAR one of the largest assets in crypto, rivalling Bitcoin's current market cap. That outcome requires Hedera's enterprise adoption to translate into on-chain transaction volume at a scale that meaningfully justifies token demand.

The more grounded question is whether Hedera's fundamentals support a significantly higher valuation than current levels. The Council's institutional credibility, the CBDC pilots, the tokenisation deployments, and the AI governance partnerships all point to a network with real utility being built. Whether that utility flows through to HBAR price depends on how tightly the fee-and-staking model connects network activity to token demand. That connection exists. It needs volume to activate it in my opinion.

Hedera Hashgraph FAQ

What is Hedera Hashgraph in simple terms?

Hedera is a public distributed ledger, similar in purpose to a blockchain but built on a different architecture called hashgraph. It is faster, cheaper, and more energy-efficient than most blockchains. It is governed by a council of major global enterprises and designed for enterprise-grade applications at scale.

How Is Hedera Hashgraph Different from a Blockchain?

Hedera uses a data structure called a directed acyclic graph (DAG) rather than a chain of blocks. In a blockchain, competing blocks get discarded and the work that went into them is wasted. In Hedera's hashgraph, every event is preserved and incorporated into a single consensus order. The result is no forks, no mining, and deterministic finality. Confirmed transactions stay confirmed.

What is aBFT and why does it matter for Hedera?

Asynchronous Byzantine Fault Tolerance is the highest theoretical security standard for distributed systems. It means Hedera can reach correct consensus even if some nodes are acting maliciously or go offline. It does so with mathematical certainty rather than probability. Most blockchains cannot make that guarantee.

Why is Hedera trending?

Several converging factors. The Reserve Bank of Australia selected Hedera as one of the platforms for its Project Acacia wholesale CBDC pilot. Hedera launched Verifiable Compute with NVIDIA and Deloitte for AI governance. The Council expanded with new members in energy and electronics. Tokenised real-world assets on Hedera have crossed multi-billion dollar thresholds. Enterprise DLT is moving from pilots to production, and Hedera is in the middle of that shift.

Why does HBAR have value?

HBAR is the fuel of the Hedera network. Every transaction, smart contract execution, and token transfer requires HBAR to pay the fee. It also secures the network through staking. As network usage grows, demand for HBAR to pay fees and stake to nodes increases. The fixed 50 billion supply cap means demand growth is not diluted by unlimited token issuance.

Is Hedera a private or public network?

The network is public. Anyone can hold HBAR, create an account, and build applications. The consensus node layer is currently permissioned, with nodes operated or sponsored exclusively by Hedera Council members. The transition to permissionless nodes is on Hedera's roadmap and has not yet been implemented.

Which big companies run Hedera nodes?

Council members operating or sponsoring nodes include Google, IBM, Dell, Boeing, LG Electronics, Deutsche Telekom, Standard Bank, Chainlink Labs, Ubisoft, the London School of Economics, and University College London, among others. The Council has approximately 31 members and is targeting 39.

How fast is the Hedera network?

Hedera's native token service and consensus service handle over 10,000 transactions per second with finality in under five seconds, at around $0.0001 USD per operation for many transaction types. Smart contract execution through the EVM layer has lower throughput. Bitcoin handles around 7 TPS. Ethereum handles around 15 to 30 TPS on its base layer.

Is Hedera quantum-resistant?

Partially. Hedera uses 384-bit SHA-2 hashes, which are considered safe against quantum attacks. Its digital signature scheme uses elliptic curve cryptography, which is not yet quantum-resistant. Hedera is actively monitoring NIST's post-quantum standards and has partnered with SEALSQ on quantum-resistant hardware integration. No current quantum computer can break Hedera's cryptography. The preparation for future threats is already underway.

Who Is Dr. Leemon Baird?

Dr. Leemon Baird holds a PhD in Computer Science from Carnegie Mellon University. Before Hedera, he held academic and research positions in computer science and mathematics, and served as a professor at the US Air Force Academy. He invented the hashgraph consensus algorithm. That is the patented data structure and consensus mechanism at the heart of the Hedera network. He has spent the years since building out its formal mathematical proofs and cryptographic foundations.

What Does Hedera Activity Mean for Your IRS Tax Obligations?

Every interaction with the Hedera network that involves HBAR or HTS tokens is a potential taxable event under IRS crypto tax guidance.

Staking rewards are generally treated as ordinary income in the year received, valued at fair market value at the time of distribution. The IRS has not issued explicit guidance specific to staking, but that treatment is derived from established crypto income principles. Daily HBAR staking distributions mean you could have 365 separate income recognition events in a single tax year. Token swaps on Hedera-based DEXes trigger a disposal event. You must calculate and report gain or loss on whatever you exchanged. HTS token receipts through airdrops or liquidity incentives are reportable income. Smart contract interactions that result in token movements create their own reporting obligations.

The IRS does not distinguish between a transaction on Bitcoin's blockchain and one on Hedera's hashgraph. The underlying technology is irrelevant, and the IRS knows about all your blockchain activity. What matters is whether you disposed of, received, or exchanged a digital asset. On Hedera's high-throughput network, active users accumulate those events faster than on almost any other platform.
